What is the keto diet?
The keto diet is a low-carb, high-fat diet that shares similarities with the Atkins and LCHF (low-carb, high-fat) diets. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis.
How does ketosis work?
When you eat carbohydrates, your body breaks them down into glucose (sugar), which your cells use for energy. However, when you reduce your carb intake, your body doesn’t have enough glucose for energy. As a result, it starts to break down stored fat into ketones, which your cells can also use for energy.
What are the benefits of the keto diet?
The keto diet has been shown to have a number of health benefits, including:
- Weight loss: The keto diet is very effective for weight loss, especially in the short term.

Tips for starting the keto diet
If you’re interested in trying the keto diet, here are a few tips:
- Start slowly. Don’t try to cut out all carbs at once. Start by reducing your carb intake to 50 grams per day and gradually reduce it from there.
- Make sure you’re getting enough electrolytes. When you cut out carbs, your body loses electrolytes like sodium and potassium. It’s important to replenish these electrolytes to avoid symptoms like fatigue, headache, and muscle cramps.
- Drink plenty of water. Staying hydrated is important on any diet, but it’s especially important on the keto diet.
- Listen to your body. If you’re feeling unwell, take a break from the keto diet.
The keto diet is a low-carb, high-fat diet that has been shown to have a number of health benefits. However, it’s important to talk to your doctor before starting the keto diet, especially if you have any underlying health conditions.
